Disappointing and dishonest
I have been with MoZillion for some time and have two sims.
Yesterday, I had a look at moving one of my sims onto a deal they linked to my account.
£4.50 pcm with a discount of 50% for three months.
When I completed the sale I received an email with the price of double that.
I called and was told that that was correct and that unlike all the other tariffs shown, this one had the discount all ready deducted.
I did agree and sent a letter of complaint with a screenshot.
Today I received an email that said
I can confirm that this deal is for new customers only.
What a load of nonsense.
Disappointing and dishonest
Monday 10/06/26
Spoke to customer service again today and it turns out that I had been talking to the same guy all the time “unbeknownst to me “
I have excepted the 12 months @ £8.50 PCM with a 50% discount for three months.
I have also asked for an official explanation as to the way this offer should work.
Just had the response from MoZillion below and as with most companies responses, meaningless.
I took an offer that was misleading and only noticed when I took the time to read the email. I was then given a number of reasons why I couldn’t have the deal that is still on the website.
I then received a response to my formal complaint telling me that it was a new customer only deal, then I was told I could have the deal after all.
Not good and if you are looking at purchasing a deal with MoZillion, check your emails and complain if you don’t get what is advertised. I shall wait and see if they amend the advertisement, if not I will report the company for deliberately misleading.

Hello, thank you for your feedback. I can see one of our Customer Team has been in touch with you to confirm that yes you do get the discount of 50% for 3 months.
If we can help with anything further, please do contact us - help@mozillion.com.
Mozillion Customer Tea,
Fantastic service!
Cristian really ‘owned’ my problem and persisted to sort it out for me. Very impressed! This could have been a shaky start to my mozillion experience but the agent turned this around so I am now an advocate. And it was really easy to get through to a human who could help - none of this bot nonsense.

Ordering was painless and easy. BUT
Ordering was painless and easy. However I expected much better connection and speeds as this is on the ee network. I have a spusu sim card which is also on the ee network and speeds are blazing fast, so very disappointing

Trying to change the port date and it's almost impossible

Reply from Mozillion
Hi, thank you for getting in touch. Once a port date is set, if it has started it is not possible to change the date as the process takes place between the 2 networks. If the process hasn't started yet then you can change the date by contacting our customer team on help@mozillion.com or by calling 020 3893 8441.

Bad non responsive customer service
Bad non responsive customer service, suspended my account with a reason that I sent more than 500 messages in a month while I only sent one message in all my 3 month contract. I proved all that but they are not providing any proof of that in detailed message breakdown but still suspended since last week and always told that the relevant person is not there to talk. Never go with Mozillion because it’s cheap but it’s all scam

Hello, thank you for your feedback. I can see that one of our customer team has been in contact with you regarding this and the line's suspension for breach of our fair use policy due to a very high volume of SMS messages which would be deemed outside of personal use - this policy exists to protect all customers on our network.
If you need any further help or info, please do contact us via help@mozillion.com.
Kind regards

Hi, SIM cards usually take 1-2 working days to be delivered, and eSIMs take around 1 hour so please accept our apologies if it took longer than this.
If we can help further, please contact us on help@mozillion.com.

Sim arrived quickly and port of my pac number took place when they said it would. Pricess was seamless. As I’ve only had the service a couple of days I don’t know what the customer service is like if I had issues but I was happy with the service provided.

Competitive pricing on the best network
Very competitive pricing on both devices and sim plans, whilst offering great network coverage with the EE network which was a must for my needs. Simple crystal clear contract pricing whilst ordering makes the experience of ordering pleasant.
